TESTING i MACHINE.

My invention 'relates to improvements in testing machines and' particularly .testing machines adapted tor testing valves, sprinkler heads7 spark plugs and' similar devices tor retaining pressure.

The object ot my inventionis to provide a machine adapted for rapidly testing devices whereby large quantities o"l` theseVV devices may be testec'l alminimum` amount'otl time a'turther 'object otn'iy invention is to provide a'machine havingmeans'tor vreadily at-y taching and detaching the devices to be teste'd;'astil1further object ot'my invent-ion is to provide a machin'e having' va constant pressure there-into which the 'devices to be tested are subjected; a'still't'urther object is to provide a machine 'ha-ving. a plurality ot outlet ports into Which a` ntnnb'er of devices maybe insertedand testedduring one revolutionof the machine; and 'a stillturther object is to embody in theninachine valves and valve operating' mechanism adapted for automatically opening and closing' the ports duringthe testing; operationot the machine` whereby 'one port Will be closed for the re# moval Aot a device 'rvl'iiich has beentested and the insertion of a `device to be tested; and the otherv ports lWill be open; thus sub'j ectinpgf-cer-r tain of the devices to' the testing` pressure;V

these together withl various other novel features ot' constr-t'iction`andy operation of the several parts, which' will be more fully here# inatter described and claimed, constitute' my l invention.

1let'e'rri'ng to the accon'ipanyingl drawings; Figzl, is acentral vertical sectional view ot my imjnfoved testing machine, as on line 1-1 Fig, 2; and Fi 2, is avert'cal sectional viewY as on line 2 2 Fig. 1.l

ln the drawings inwliich like reference characters re'ler to like parts,` 1 and 2 repre# n sent bearings in which is rigidlysupported a shait 3. Rotatably `mounted'up'on the shait 3 is a casing 5, comprising an annular body portion 6 tightly secured by bolts 7 to end disks 8 and 9. Said disks' are provided with central bearing sleeves 127` rotatably mountn ed upon the shaft 3 andprovided With stutl'-A ingl boxes l3`i`or preventing leakage' ot the pressure medium from'. the chamber 15, formed within the casing' 5. Said pressure medium may be air, oil, water, or the like, which isf conveyed tov said chamber through the passageway 16 and the other openings 17y and 18 formed in the shaft 3,

diamctrically opposite each other and se-V cured in their adjusted positions in relation to the body portion by lock nuts vPtfotatably mounted upon each valve sleeve lis a securng member 30, adapted 'for attac-hing;` a device to be'teted andtightly l'iolding the same uponthe end ot' thevalve l sleeve' 'Said securing member 3()l consists'of a hand Wheel 31 adapted to rotate freely npon'tb'eenlarg'ed head 26or1ned upon thevalv'e sleeve 24. Cheek platesr 32 and 325 are secriredupon opposite'sides ot the hand wheell by bolts 35,` and engage opposite tacesiot thev head 26, thus perniitting the securing` member `to rotate freely upon vthe head 2b"r and also preventing" any niovement'ot' the' sec-uring'member 30, in relation to the longitudiiialanis of the valve sleeve 24'; The outer cheeky plate 32 isprovided with a threaded aperture 36,- adapted to lia-vea device 23 screived into saidl aperture 36, by rotating` the khand;Wheel iure# lationk to" the device' 23, thus tightly clamping the device 23 upon vthe packing Washer 27 Vembedded' in arecesstorined in the end surface of thefvalve sleeve 24. so as to lprerventl any leakage of pressure between-the device Q3 andthe end ofthe valve seevee,v The valve sl'eevy 2st is'v provided with' a portQSand also a conical5 valve SeatQQ. fr conical valve ellis provided to engage said seat 29 and close the port-'28. Thefbody ot' the valve il() is provided with gru-ide luas *il which hold theivater `valve centrally in lthe va'lvesleeve 24. A valve rod #LQ is secu'redfin a sleeve forming part of 'a collar i5 having anelongated aperture lli"\vliich lis occa kpied by an eclcentricfl` upon the shaft then thefcasing 5r is rotated about the eccentric 48, ythe collar Ll'ivill move the valve 40 to and' from -the valve* seat-29, and"A open' and close the port 2S formed in the valve sleeve, communicatingr with the device 23 to be tested. l In they form" ot my invention' shown in the drawings,V tivo valvesl@ and 405 are' mounted'in alignment upon opposite sides lll) of the collar 45. Thus the casing is rotated about the eccentric LiL-S, when one valve will be in the closed position 1the opposite valve will be in the open position, the latter valve admitting the pressure medium to the-device Q53 to be tested.

rihere are also two collars and 4:5 shown in the drawings for operating two valves e0, thus providing a machine L d to receive four devices to be tested. The collars af and i5-l are mounted upon the same eccentric fl-8 which is of sufficient length to extend through both collars. The collars d5 and so are placed side by side within the casing and the valve rod sleeves are oily-set so that` all the valve rods and valves will be positioned in the same plane. 'ihe valve rods d2 are threaded in the sleeves i3 and also secured pins 19 to prevent their turning axially.

`The valve 40 and the valve seat 29 may be relatively adjusted by screwing the threaded portion of the valve sleeve 2d, into the body portion G and then securing said sleeve by the lock nut 25, thus providing` means for adjusting the valves without the necessity of having access to the interior of the casing 5. The eccentric i8 is provided with two apertures 17 and 18, so as to prevent the collars from at any time closing ofi' the supply of pressure from the hollou7 shaft By this arrangement one of said apertures will always be uncovered.

rl`he operation of my invention is as fol- L Y Uf I lows The devices 23 to be tested are screwed into the securing members 230 by turning the hand wheels and holding the devices from turning. The pressure, either air or water, is admitted to the chamber l5, of the casing 5. The casing 5 is rotated by hand about the shaft 3, and as it is rotated the eccentric will open and close the valves, The valve shown at the top of the drawings is in the closed position and when so closed a device 23 to be tested may be inserted or removed without pressure escaping through the port 2S. The remaining valves, as shown in the drawings, are in the open position thus admitting the pressure to three of the devices to be tested.

Then air is used as the medium for testing the devices a pan 5() is provided containing water so that any leaks in the devices may be readily detected as they are turned around with the casing and are submerged in the water. Then Water is used as the testing medium this pan is not necessary as a water-leak will show upon any imperfect device.
